I figured I would try to make a list of the combos that cause huge swings in board state or amber so that people can watch for them. Not including combos that are just 2 large effects on 2 cards (Gateway to Dis + Arise), or combos dependent on your opponent (anything with mimicry). Cards you have to hope aren't destroyed for a turn are okay.
Board Wipe + Loot the Bodies
Autocannon + Soul Snatcher + Bad Penny
Witch of the Eye + Inspiration
Library Access + Nepenthe Seed
Tendrils of Pain + Cleansing Wave
